About O&O <strong>DiskImage</strong> 7<br />

Image file<br />

An image can be made up of one or more image files (*omg). If, for example, the disk where you want to save the image<br />

isn't large enough, you can split the image onto multiple disks. When you split your image onto several disks, a new<br />

image file will be created on each disk and together, these image files will be parts of one entire image. It's important to<br />

number the disks (CD/DVD) in case you want to later restore a drive using the image, or use it as a base for an incremental<br />

imaging.<br />

File formats<br />

O&O <strong>DiskImage</strong> creates its own file formats when imaging but is also able to process other file formats.<br />

File format OMG<br />

O&O <strong>DiskImage</strong> generates the file extension (*OMG)for the image files it creates when imaging your entire computer or<br />

single drives. This file type can be used for further activities by O&O <strong>DiskImage</strong>, such as restoration, validation or conversion.<br />

File format OBK<br />

While creating a file backup using O&O <strong>DiskImage</strong>, the files and folder are compressed and stored as OBK file (*.obk).<br />

An advantage of the OBK files are that you can also use and extract the data with a decompression program like Win-<br />

Zip. You don't necessarily need O&O <strong>DiskImage</strong> to extract these files. Encrypted file backups are the exception. They<br />

can only be processed with O&O <strong>DiskImage</strong>.<br />

File format VHD<br />

O&O <strong>DiskImage</strong> is able to create and edit file formats for virtual computers (VPC/VM-Ware). This allows you to also<br />

mount a drive from an image as a virtual drive in the VPC or your VW-Ware.<br />

Complete image<br />

Using the Complete image method, the data selected for imaging will be imaged all over again and stored in a folder on<br />

the target disk. Complete images can be created using the "Used sector", "Forensic", or "Direct forensic" methods.<br />

Differentiation: Image of the changes<br />

If you only want to image changes of your hard disk or drives, you will need to have created at least one complete<br />

image previously. Changes made can then be saved as differential and incremental images.<br />
